Interesting discussion from another forum. Basically pick two items that would be a priority to stockpile. Don't mistake this for "these are the only two items you can have", but simply deemed the most critical for survival and thus are pillaged and taken en masse on day 1. To me I thought my answer was pretty clever: Generators and Gasoline. Basically break into all the local hardware stores and make a few trips with the truck to stock up on generators and collect gas. While the first obvious choices would be food and water, I imagine that those, along with everything else should be relatively easy pickings if you were the only one around. Generators would basically give you quality of life. They can run your entire house for air and heat as well as charge other items without relying on solar equipment. I figured with a decent stockpile of gas and generators you could live comfortably into old age barring any major medical problems.
